> Now that we have pluggable codecs (well, PostingsFormat), an app should use a custom
PostingsFormat if it really must change payloads while merging.
> Alternatively, use a FilteredIndexReader to modify anything during addIndexes (eg the
facets use case, modifying payloads).
> Since this capability can be handled by existing more-generic functions I don't see why
we need to keep PPP around in core. PPP is also fragile because an app generally has no visibility
on when a merge commits so it can't know if the payloads it retrieves are pre or post PPP.
> I think merging shouldn't change postings as a side-effect (by default, anyway, since
a custom PF can of course override merge and do whatever it wants).
